Measurement of On-Road Vehicle Emission Factors in the California South Coast AirBasin. Volume 2. Unregulated Emissions

摘要

The purpose of the Southern California Air Quality Study (SCAQS) project was tocharacterize the particulate and gaseous emissions (both regulated and unregulated) from motor vehicles in the South Coast Basin during the last half of 1987. The characterization was used to provide updated motor vehicle emission factors, which would then be available as inputs to the air quality simulation models. The final report describes the measurements of unregulated mobile source emissions in a parking garage and tunnel. The unregulated emissions measured were: hydrocarbons, from C1 to at least C10, carbonyl compounds, alcohols, carboxylic acids, organic and elemental carbon particulate matter, particulate matter by element, and sulfate.
